@Ave I'm a geek. ;p

I'm a hardware enthusiast ;)

I'm a cat

and also a big sweaty American guy

I'm just zis guy, you know?

@bwDraco 5G will be nothing more than a gimmick for almost a decade.

At which point they'll probably just give up on the tech because tbh it's pretty unnecessary for most use cases, and too ridiculous to implement.

</speculation>

@rahuldottech lol

Low-frequency 5G is going to be broadly deployed and will replace LTE over time. High-frequency (mmWave) 5G will be much harder to deploy due to its very limited range; that is what will enable the dramatic increase in bandwidth available. The 5G NR air interface is designed to support extremely large number of devices; this means that regardless of the spectrum used; performance in scenarios like crowded transit terminals and massive IoT communications will see substantial improvements.

Device capacity is only part of the story, though.

Until the high-frequency 5G cells are widespread, the performance advantage visible to the end user is going to be limited. We're probably going to see these mmWave cells in places like crowded transit terminals and sports arenas first precisely because that's where the highest demand for bandwidth is.

Users will see performance improvements both upon initial launch of 5G service and over time, but it'll probably take 5-10 years and massive investments for the full benefit to be realized by the majority of users.

> Simulation of standalone eMBB deployments showed improved throughput by 2.5× below 6 GHz and by nearly 20× at millimeter waves.

The thing that matters for the next couple of years is going to be that 2.5× number. As mmWave cells proliferate, we'll see performance ramp up dramatically.

Regardless, I'm going to be upgrading from an LTE Cat. 6 device, which is actually pretty anemic when you compare it to the "gigabit LTE" (Cat. 16) devices currently available.

While my mobile carrier (T-Mobile) has been busy adding mid-band (bands 2 and 4) spectrum capacity across New York City and elsewhere over the past several months, resulting in visible improvements in cellular data performance (both bandwidth and latency) even on this old (2016) device, it's going to pale in comparison to a modern Cat. 16 gigabit LTE device, let alone 5G.

support.t-mobile.com/docs/DOC-4988

My phone supports bands 2, 4, and 12. It doesn't support bands 66 or 71.

(band 5 is less relevant here)

IMO 5G will produce user-visible benefits within two years, but it'll take another two to five years for the benefits to be fully realized.

anyone alive here who remeber me? :P

lol

I've seen you here a few times before.

@bwDraco lol I was very active once upon a time :D

I think you might have known me by the name of DragonLord back then...

Yes, I'm still the same dragon.

@bwDraco Yes I remember that name

@bwDraco lol I don't think you are the same now it seems you got old too :D

@avirk yup.

Hey @avirk! Long time no see!

Hmm... trying to yum udpate and I get this:

** Found 114 pre-existing rpmdb problem(s), 'yum check' output follows:

@MichaelFrank Make a copy of the rpmdb, then run rpm --rebuilddb.

along with a big list of apparent duplicates.

@bwDraco like so? tecmint.com/rebuild-corrupted-rpm-database-in-centos

Sorta. Make a tarball of the contents of /var/lib/rpm, then run rpm --rebuilddb.

Hmm... haven't seen or used the procedure there before.

I didn't realize there were commands there for maintaining and validating the rpmdb.

bleh... didn't seem to work.

ERROR [dcrpm.run]: Unable to repair RPM database

what a fun error!

github.com/facebookincubator/dcrpm/blob/master/…

Okay, luckily the suggestions here seem to have worked.

downloading updates now.

@Bob bhu... wha?

> Brexit is something that Britain has done to itself. Britain is basically Pompeii, if Pompeii voted for the Volcano.

@JourneymanGeek who dis

@avirk old user. Not like you... Whippersnapper ;p

@JourneymanGeek THREE YEARS. THREE LONG YEARS I HAVE BEEN A PART OF THIS CHAT ROOM. DO THEY MEAN NOTHING TO YOU!?!?!?!?!?! HOW CAN YOU JUST DISREGARD IT ALL!?!?!?!?!!??

If thou would vacate my small domestic field of grass ... ;P

@bertieb how's that work tho. As to join a party on playstation, I need an invite which comes via PSN...

I know we can play against each other

of course there was a big update to the game, so that may of changed things but I've not played since.

inb4 i get suspended again for ascii

@JourneymanGeek hey man how are you?

@CanadianLuke yeah man thinking to come to Canada to meet you now a days :D

@JourneymanGeek not more older than you lol

Alright

I'm a 2 site mod now ;p

@JourneymanGeek damn so much improvement without me, I am happy I have a good apprentice like you :P :D

morning

Ok so I've seen that in a few malls around here

There'll be a sticker on a ladybug in the urinal

And I'm always just like wut why

Or a fly

Only just learned that it's there so that dudes instinctively aim at it

Apparently it improves aim

Yeah

i go for the minigun approach

@Burgi What approach is that?

Multiple.... Oh dear

spray and pray

hahahah

@djsmiley2k I dunno, there was a big overhaul; you now can get party invites in-game

on PC you used to get them via Steam / overlay

Now there's a bit in the main menu / pause screen

Inspired by this superuser.com/questions/1408123. Should a Linux user/geek know script syntax of every "pid = 1" systems? I'm familiar with systemd .service file.

@bertieb oh sweet.

@Biswapriyo no

Most of them are simple and short lived enough for it to be a waste.

Just learn the one you use when you need to

Like who uses upstart?

@JourneymanGeek Ubuntu? I guess?

@JourneymanGeek thats what rahul uses ;P

@Biswapriyo not any more

you only need know how to read a man file

@Burgi He's a machoist tho

he is an upstart though

another joke that everyone ignored :(

;)

@Burgi wait what

@Burgi oh I groaned

I'm not getting it (¬_¬)

You heard the joke about UDP?

You never get it?

@CanadianLuke I believe I have:

Looking at their discussion of OFDMA, it seems this technology enables overlapping time slices. Am I understanding this correctly?

I've always understood this as simply a way of encoding data that allows the router to handle more devices at the same time, but I'm not too familiar with how it works.

(enhanced MU-MIMO in 802.11ax is not a mystery to me, and I'm well aware that the new standard allows up to eight devices to share a time slice)

blog.aerohive.com/the-main-ingredient-of-802-11ax-ofdma

Interesting.

Maybe @FMLCat (our resident wireless expert :P) understands this better?

(somebody tell @FMLCat that I no longer need to be blocked)

> OFDMA subdivides a channel into smaller frequency allocations, called resource units (RUs). By subdividing the channel, parallel transmissions of small frames to multiple users can happen simultaneously.

Oh, wow. So basically, the router can use small bits and pieces of the spectrum to communicate with multiple devices simultaneously?

I think OFDMA will make its presence most felt in busy gaming environments, where you have lots and lots of small packets getting moved around.

@djsmiley2k ^

good job

Hmm. Blogger says three hits came from t.co.
